April 30: Here is a sample final exam; note that it is comprehensive but covers the latest material more heavily. In addition, here is the cheat sheet that will be provided on the final.

April 26: No office hours this week from me at all. Please see your substitute, Dr. Jason Fritts (jfritts@slu.edu, in office 233 Ritter Hall, with any questions.

April 23: Homework 9 is available; it will be due on the last day of class, Monday, May 3.

April 19: Please omit problem 1g from homework 8; it covers a topic we didn't really discuss in class, so you do not need to include it. Feel free to consider it an extra credit problem instead.

April 16: Homework 8 is available; it will be due next Friday, April 23.

April 9: Homework 7 is available; it will be due next Friday, April 16.

March 30: The cheat sheet for midterm 2 link has been updated with the corrected version of Master Theorem. Also, there was a bug on the homework 6 solutions, in problem 4a, where n4^n should become (c4(n)+c5)(4^n).

Here is the cheat sheet you will be provided for midterm 2. (If it's missing anything, please contact me ASAP and I'll consider changes.)

March 24: Midterm 2 will be in one week, Wednesday the 31st, during class. Here is a sample midterm covering similar material from a previous incarnation of this course. While the midterm will focus on material since the last exam (particularly big-O, pseudocode, and recurrences), material from the first part of the course is also possible.

March 3: Homework 6 is now posted. It will be due by the start of class on Friday, March 26. Please note that it may be submitted in pairs, if you wish to work with a partner.

March 17: I am changing my Thursday office hours for the rest of the semester, since doctors appointments are getting more common now. I'll keep them on the same day of the week, but instead of 1-2, I'm moving them to 9-10am every Thursday. (Keep in mind that I'm often around later than that, but I will definitely be in 9-10.)

March 4: Just a reminder that my office hours today will not be from 1-2 due to a doctor's appointment. I will be in 11-12 instead if you would like to come by, or can arrange another time if you email me.

March 3: Homework 5 is now posted. It will be due by the start of class on Wednesday, March 17. Please note that it may be submitted in pairs, if you wish to work with a partner.

Feb. 29: I will have to shorten my office hours tomorrow, on Monday the 29th, since my daughter is home sick. I will still be in 10-11, but will not be able to stay the entire morning in my office. Please email me with questions or to make alternate arrangements to meet.

Feb. 22: Homework 4 is now posted. It will be due by the start of class on Monday, March 1. Please note that it may be submitted in pairs, if you wish to work with a partner.

Feb. 15: Apologies for the late notice, but I'll be in late this morning due to snow. I'll reschedule office hours as needed, so please email me to make arrangements.

Feb. 12: Midterm 1 will be next Wednesday in class. Here is a sample midterm; note that the length and/or content may be slightly off from what we've covered, since it is based on a previous version of this course, but it should give you an idea of what to expect on the exam.

Feb. 5: Homework 3 is now posted. It will be due by the start of class on Friday, Feb. 12. Please note that it may be submitted in pairs, if you wish to work with a partner.

in my office before 5pmon Tuesday to recieve full credit. (If I happen to be out when you stop by, just slide it under my door.)

Please note that it may be submitted in pairs, if you wish to work with a partner.

Jan. 20: I'll have to leave my office hours a bit early today, due to a faculty meeting that was scheduled at 11am. Instead, I'll arrange to be in my office from 12-12:30, after the meeting is over.
